DRAFT SILL.

Application filed July 3,

This invention relates to draft rigging for railway cars, and moreparticularly to the draft members thereof.

(lne of the objects of the invention is the provision of a new andimproved wear plate or shoe for draft key slots for receivingthe wear ofthe draft key incident to the operation of the draft gear.

Another object of the invention is the provision of new and improvedwear plate or shoe for key slots of draft arms or other draft members,together with new and in1- proved means for detachably retaining theshoe in position, whereby it may be readily replaced when necessary ordesirable.

A. still further object of the invention is the provision of a new andimproved wear plate o1' shoe for the key slot of draft members,y that issimple in construction, effective in use, cheap to manufacture, that maybe readily attached or detached, and that is se* curely held in positionby an extremely simple arrangement.

Other and further objects and advantages of the invention will appearfrom the following'description taken in connection with the accompanyingdrawings, in which Fig. 1 is a vertical section of a portion of one endof a car, showing the invention in position thereon;

Fig. 2 is a section on line 2-2 of Fig. l;

Fig. 3 is a section on line 3-3 of Fig. 1;

Fig. 4 is a section on line 4-4 of Fig. 1;

Figs. 5 and 6 are longitudinal sections similar to Fig. 2 but showingmodified'forms of the invention;

Fig. 7 is a section similar to Fig. 3, but showing a modified form ofthe device.

Reference now being had to the drawings, in which similar referencecharacters designate the same parts throughout the drawings, the numeral10 designates the under- `flaming of one -end of a railway car and 11one of the draft members extending' longitudinally of the car in theusual manner. The draft member l1 provided with thel draft lug 12 andthe draft key slot or opening 13, as is usual in such constructions. Thedraft lug l2 is preferably reinforced by triangular ribs or gussets 14and 15 extending horizontally inwardly from above and below said slot 13in the usual manner.

It is understood that there are two draft members 11 extending parallelwith each other in spaced relation. but since they are alike exceptbeing rights and lefts, and

1926. Serial No. 120,494.

since the construction is old in the art, it is not thought necessary toillustrate or de,- scribe more than one of the members. 'Vliic sectionof the device shown in Fig. 1 is in a vertical plane between themembers.

ln the conventional type of draft gear rigging the continued movement ofdraft key in the draft key slot will in a coinparatively short time wearthe material at the lower margin of the slot, and as a result the gearwill not have that smoothness of' action that is desirable in draft gearcon struction. The present invention contein plates the use of shoes orwear plates that may be readily and cheaply replaced when the samebecome worn.

In the form of the device selected to illustrate one embodiment of theinvention. a shoe or' wear plate 16 is provided for what for'convenience will be termed the marginal wall of the' slot, to protectthe same. Suitable means are provided for detachably molmting the'shoe16 in position. As disclosed in Figs. 1, 2, 3 and 4, the slot 13 isoffset at its lower portieri to form a notch 17 having' vertical walls13 and 19. These walls are preferably though not necessarily providedwith vertical V-s'hapcd grooves 21 and 22, see Fig. 2.

The marginal wall of the notch 17 is rabbeted to form the opstandingflange 9.3. The shoe 16 is provided at each end with V- shap'ed tonguesQ4 and 25 for engaging the V-shaped grooves 2l and Q2 respectively. Thelower portion of the shoe is rabbeted to fori'n a downwardly extendingflange 26 which is adapted to engage the rabbet in said4 marginal wall.The flange 26 is arranged' to extend downwardly on the inner side' ofthe draft member in order that the same may prevent displacement of theshoe 1'6 by the engagement and hammering of the saine by the couplerhead or yoke during? the travel of the/cai".

The reinforcing rib or gusset 14 is provided with a groove 27 forreceiving the downwardly extending flange 26 of the shoe 16 (see Fig.4). If desired the flange 26 of the shoe 16 may be provided with anextension 28 for engaging a corresponding recess in the lower marginalwall of the slot 13. An alined aperture is provided through theextension 28 and the flange 23 through which a fastening means such asthe rivet 29 may be inserted for preventing vertical movement of theshoe. It is under- 'l is removed and the shoe slid downwardly intoposition with the tongues 24 and 25 engaging the grooves 21 and 22,after which the key may be re-inserted.

The modified form of the device shown in Fig. 5 differs from that shownin Fig. 2 in that the tongues 3l and 32 at the ends of the wear shoe 33are rectangular instead of V- shaped and are adapted to engagecorrespouding grooves in the walls 34 and In Fig. G the tongues 36 and37 of the wear shoe 88 are substantially the same as that shown in Fig.except that the outer portion of the tongue is curved instead ofrectangular.

In Fig. 7 the lower marginal wall of the slot lil is provided with agroove 39 for receiving a corresponding tongue 41 on the wear shoe 42.In the construction shown in this figure the tongue is V-shaped but itis understood that it may be of any suitable form in cross-section.

IVhen the shoe becomes worn the draft key is removed, the worn shoelifted out, a new one dropped in position, and the draft key reinsertedin the slot 13.

It is thought from the foregoing taken in connection with theaccompanying drawings that the construction and operation of my devicewill be apparent to those skilled in the art, and that various changesin size, shape. proportion and details of construction may be madewithout departing from the spirit and scope of the appended claims.

I claim as my invention:

l. In draft rigging, a draft member provided with a draft key slotadapted to receive a draft key, a wear shoe engaging the lower marginalwall forming said slot, said lower marginal wall and shoe being providedwith interengaging portions for preventing endwise and lateral movementof said shoe on said sill, but permitting the removal of said shoe by avertical movement whereby said shoe will be held from removal by saidkey when the latter is in position in said slot.

2. ln combination, a draft member provided with a key slot, said slothaving an offset at its lower side terminating at each end in grooves, awear shoe mounted in the offset portion of the slot and having a tongueon each end for engaging said grooves.

3. A draft member having a key slot therethrough, the lower marginalwall of said slot being offset downwardly and rabbeted, each end of saidoffset portion being provided with a V-shaped groove, a wear shoe havingits lower edge rabbeted complementary to the rabbet in said marginalwall and engaging the same, and having its ends provided with V-shapedtongues for interlocking with said grooves.

4. A draft member having a key slot adjacent its outer end, a draft lugadjacent said slot, a reinforcing rib for said lug, said lug beingprovided with a groove, a wear shoe for protecting the lower marginalwall of said slot, said shoe being provided with a flange for engagingthe groove in said rib.

A draft member having a key slot therethrough, the lower marginal wallof said slot being offset downwardly to form a notch, the end walls ofsaid notch being provided with vertical grooves, a wear shoe forengaging said notch and having its ends provided with tongues forengaging said grooves.

G. A draft member having a key slot `therethrough, the marginal wall ofsaid slot being rabbeted on its inner side to form an upwardly extendingflange on the outer side, a wear shoe rabbeted to provide a flange forengaging the rabbet in said wall, and interlocking connection betweenthe ends of said shoe and said wall.

7. A draft member having a key slot therethrough, the lower marginalwall of said slot being offset to form a notch terminating at its endsin grooves, said lower wall being rabbeted, a wear shoe having tongueson its ends for said grooves and being rabbeted on its lower portion toengage the rabbet in said wall, and fastening means extending throughthe overlapping portions of said wall and shoe.

In testimony whereof I affix my signature.

CHARLES MELVEN HOUSE.
